H3D size reduction

Hi,

I have a large assembly model but I'm only interested in the performance of a single part. I've reduced h3D file size using all the standard methods (only exporting the stresses in the part of interest and at the final iteration) but the file size is still too large. Is it possible to reduce the H3D file size by only exporting a specific component in a model?

Kind Regards

Jamie

    The h3d file contains all the model data so besides using hvtrans your best bet is probably to use some other output type to get just the information you want.  For example you could use STRESS/ELSTRESS and set the option to opti (to get the results in a .strs file) and define a set for which you want those results and then you would just have stress for the elements you want in one small file.

    This is is the best way to call only particular elset set , when we know the area of interest .

    Also, Further  we need to  reduce the h3d file   , then if your are  not interested to see intermediate results . then you can use  NlOUT  use NINT =2.
